Of course you can. It's comparing the top 10 supported clubs in NI with the top 10 supported clubs in ROI.
I mean, if the IL only had, say, 8 teams, but the LOI had 16, would you consider a simple average for each league as being valid for comparative purposes?
Absolutely not so.
UCD's crowds were closer to the teams above them, in relative/percentage terms, than Stute and Point were to the teams above them. and that's ignoring Harps, who were closer again to the next lowest team (Waterford).
[And don't forget that flooding forced Stute to move from their home ground in Drumahoe to the Brandywell, which must have hurt their attendances even further.]
Really?
When the league was suspended, LFC were four points ahead of Coleraine, with 7 games still to play. And since the league split after 22 games, those games were all against the other top five teams, inc. Coleraine.
Meanwhile, there were only 3 points separating teams 3rd to 6th, in the chase for a possible European place.
In any case, crowds have been rising season-on-season for several years now, irrespective of how competitive each has been.
Cliftonville play Glentoran and Ballymena play Coleraine in a double header behind closed doors at Windsor on Mon. 27 July.
The final is at the same venue on the following Friday (31st). It is just possible that some fans may be allowed into the final, though I'd say it's still (long) odds-against, not least because it's being televised live on BBC NI (also the two semi's).
